Calories and Portions

An appropriate serving size is one-eighth of a pie with a 9-inch diameter or one-sixth of an 8-inch-diameter pie. One slice contains between 277 and 296 calories, depending on the size of the pie. A total of 57 percent of the calories come from carbohydrates, 42 percent from fat and 3 percent from protein. You'll also consume 18 to 20 grams of sugar in a single piece. Eating excessive amounts of calories can lead to obesity and chronic diseases. So try to save apple pie for special occasions to help promote a healthy waistline.
